Arsenic Sulfides TRIZ Cases
- Stepwise Sulfidation Control for High-Arsenic Copper Smelter Waste Acid
Real-time arsenic valence monitoring guides staged hydrogen sulfide dosing to cut filtrate arsenic and toxic gas emissions.
- Arsenic Separation in Copper Smelting Acidic Wash via Oxidation
Oxidizing arsenic with hydrogen peroxide prevents copper co-precipitation during sulfide treatment.
- Arsenic Sulfide Nanostructure Biogenic Production via Fusibacter
Fusibacter ascotence cultures convert arsenic and sulfur into monoclinic arsenic sulfide nanowires and nanoparticles.
